Longsys Debuts at MWC25, Unleashing the Power of Storage Innovation in Mobile Communications

On March 3, Longsys made its first-ever appearance at MWC 2025 in Barcelona. Under the theme "New Mode of Storage Empowering Global Mobility", it showcased a series of innovative storage products, attracting widespread attention.

As a branded semiconductor memory enterprise, Longsys has always adhered to the concept of technology-driven innovation to empower the development of the industry, and has continuously introduced new technologies and products to create more value for customers.

PTM Business Model: Full-Stack Customization Service

The Product Technology Manufacturing(PTM) model was a major highlight, showcasing Longsys’ full-stack customization capabilities—from in-house controller development and product design to rigorous testing and intelligent manufacturing.

Embedded Storage for Mobile Devices: Unlocking Flagship-level Performance
Longsys presented a full lineup of embedded storage solutions for smartphones, tablets, and wearables, including high-performance UFS, QLC eMMC with in-house WM6000 controller, and low-power LPDDR5. These products cover diversified needs from entry-level to high-end, providing all-round embedded storage support for mobile intelligent terminals.

In 2024, Longsys took the lead in applying the advanced 3D QLC technology to its eMMC products and launched the QLC eMMC that supports capacity options ranging from 128GB to 512GB, meeting the needs of "cost reduction and capacity expansion" for terminal applications. At present, it has been applied in various types of smartphones.

Under the PTM business model, the QLC eMMC is developed based on Longsys' in-house WM6000 controller. It adopts a unique QLC algorithm, LDPC error correction algorithm, and self-developed software architecture. The overall performance has been improved by more than 30%, and the standby power consumption reaches the level of microwatts (uW), which greatly enhances the battery life of the device. In addition, in response to the requirements of special scenarios, the product can adjust the logical partitions, providing better protection for the file system. Moreover, by writing the Host data in a classified manner, it ensures the security of the partition data, providing customers with precise and efficient storage solutions.

QLC NAND Flash, with its high storage density and low cost per gigabyte, has been driving the continuous increase in market penetration. The QLC eMMC is expected to be widely applied in more mobile terminal devices, further promoting the popularization of large-capacity 5G intelligent terminal devices.

Server Storage: Powering AI Computing, Accelerating Intelligent Future

In 2025, large model technology will transition from probabilistic generation to strong reasoning ability, driving the demand for higher storage requirements in data centers and cloud computing industries. The server storage products showcased by Longsys at this exhibition can effectively meet the needs of AI servers in large-scale data processing and high-efficiency computing operations.

In the server storage area, Longsys has built a rich portfolio of products covering NVMe/SATA eSSD, CXL 2.0 memory expansion modules, and DDR5 RDIMMs.

• ORCA 4836 NVMe eSSD & UNCIA 3839 SATA eSSD – Built with 3D eTLC NAND and enterprise-grade controllers, capacities ranging from 480GB to 7.68TB, ensuring high throughput, stability, and data security.

• CXL 2.0 Memory Expansion Module & DDR5 RDIMM – Supporting PCIe 5.0, up to 192GB capacity, and 6400Mbps speeds, theoretical bandwidth of 32GB/s, enabling memory pooling and AI acceleration.

Longsys Server Storage has further enhanced its comprehensive competitiveness through in-depth cooperation with benchmark customers in a number of industries, such as artificial intelligence, communication carriers, finance, and the Internet. With the global popularization of AI reasoning large models, Longsys is expected to usher in broader development opportunities in this trend.

Bluetooth PSSD: Seamless Unlocking of Hidden Storage Space

The Bluetooth PSSD stood out as a highlight during live demonstrations. This slim-profile device combines ultra-low power consumption (standby power as low as 1.5mA) with shock/vibration resistance. Equipped with a USB 3.2 high-speed interface supporting both BOT and UASP protocols, it offers configurable capacities from 128GB to 1TB.

The product supports Bluetooth 5.2 protocol and backward compatibility, as well as a unique authentication mechanism and partition management. Under regular use, users can only access part of the storage area, while specific storage areas need to be connected and paired with specific devices (e.g., cell phones, tablets) before they can be unlocked for data access. Users do not need to repeat the operation after the first pairing, as long as the authorized device is nearby, the device can be automatically unlocked for seamless access. When the user leaves the device at a certain distance, the specific storage area will automatically enter a protected state to ensure data security.

NFC PSSD: Tap to Unlock Hidden Storage Space

Similar to the Bluetooth PSSD, the NFC PSSD also focuses on privacy data protection, but is unlocked using NFC technology. Users simply tap the sensor area with an NFC-enabled smartphone, smartwatch or NFC card to unlock a specific storage area for data access, creating on-the-go privacy storage for users. The product was first announced at CES 2025 in January.

In the future, with the advancement of the PTM business model, customers will be able to combine innovative storage with the automotive, home appliance and other sectors in a more creative way through the Internet of Things, bringing a more intelligent and convenient experience to users.

Lexar Mobile Imaging Storage: Professional Photography at its Best

In the field of mobile phone imaging storage, Lexar, a consumer storage brand under Longsys, presented the SL500 portable solid - state drive and the Professional Go solid - state drive photography kit specifically designed for iPhone photography.

Lexar SL500 Portable SSD with Magnetic Set

The product is widely compatible with a wide range of devices, providing up to 4TB of storage capacity. With the unique magnetic design, it supports the iPhone 15 Pro series and 16 Pro series to externally record ProRes 4K videos and store them as they are taken without occupying the phone's memory, which is a great convenience for users.

Lexar Professional Go Portable SSD with Hub

The product adopts Mini small size design, one plug and shoot, easy to realize external recording ProRes 4K video, instant transmission, shooting material directly to the hard disk. Used in conjunction with the docking station, advanced professional photography, one-stop to meet professional needs such as sound and fill light, ideal for professional photographers.

Global Presence & Localized Services

Longsys continues to strengthen its global footprint. The product manufactured by its South American manufacturing and operations center, Zilia, gaining strong recognition at MWC. By integrating a dual-circulation supply chain strategy, Longsys ensures efficient production, stable supply, and localized support for global customers.
